v THERAPEUTIC LAMP.

Application filed November 29, 1924. Serial No. 752,998.

My present invention relates to a source of ultra-violet light for.therapeutic uses and particularly to such a source adaptable for 1plication is shown in vertical section the source of ultra-violet lightof my invention as applied to an arm for example showing means forapplying pressure to the part to be treated, means for varying exposurearea,

and means for cooling the light source.

In the drawing the jacketed lamp casing l is held to the arm 2 by meansof the straps 3, the Window portion 5 of the lamp being heldby said stras 3 to that portion of the arm to be treated? Said window portion 5 comrises an iris diaphragm which is collapsible and openable for thepurpose of var ing the exposure area, the device being hel by saidstraps 33 or equivalent means to the part'to be treated in such a mannerthat the boundary of the opening 6 of said iris 5 is held tightlyagainst the tissue surrounding the part to be treated. The insulatedmembers 88 pass through the jacket wall of the container '1 and carrytherethrough the terminal leads 9-9 which end' in suitable electrodeterminals 10-1O properly spaced from'eac-h other within said casing 11.The inlet pipe 12 and the outlet pipe 13 serve to admit cooling materialsuch as water to and from the jacket of the casing 1. The pipe 15passing entirely through the casing 1 and opening into the interiorthereof serves to admit hydrogen into the interior of said casing 1 andagainst the tissue to be treated for the purpose of dehematizing. Thegauge 16 on pipe 15 serves to indicate the pressure applied to thetissue to be treated.

In the use and operation of the device of my invention the lamp casing 1is attached to the part to be treated as by means of said straps 33under the proper tension and pressure and a cooling liquid is startedcircuof said pipes 12 and 13. Pressure is then applied to the art to betreated by admitting hydrogen or example into the interior of thecasing 1. which at the opening 6 is lating through the jacket thereof bymeans,

bounded by the tissue to be treated. The lamp casing 1 being heldagainst the tissue to be treated by said straps 33 or equivalent meansit is ossible to obtain a practical holding of the ydrogen underpressure in the lamp casing against the part to be treated. Current isthen applied to the leads 9, 9 of the electrode 10, 10 from a suitablesource for the producing of an arc for the production of ultra-violetlight, the hydrogen being a transmitter of ultra-violet light and alsoserving as means for insulating the part to be treated from the heat ofthe are.

In the apparatus and method of my invention I employ the atmosphere,hydrogen for example, as a suitable medium in which to generatethe'ultra-violet light producing are, as means for applying pressure tothe part to be treated, and as a cooling medium. In some cases I use thehydrogen for cooling without'employing the medium such as water in thecasing jacket. Flow of hydro gen when desired to secure the desiredcooling effect I produce by permitting the hydrogen to escape around theedges of the opening 5 or when desired or required I provide anotherpipe for its exit.

I claim:

1. A therapeutic apparatus including a holder member having an aperturefor application to the part to be treated, a source of ultra-violetlight within said holder and means for applying a gas under pressure tothe part to he treated at the area confined by said opening.

2. A therapeutic apparatus including a holder member having an aperturefor application to the part to be treated, a source of ultra-violetlight within said holder and means for applying a gas under pressure tothe part to be treated at the area confined by said opening, and meansfor cooling said casing. 1

3. In a therapeutic appliance a jacketed casing, inlet and outlet pathsfor distributing cooling fluid through the jacket of said casing, asource of ultra-violet lightin said casing, an opening in said casing,and a pipe to the interior of said casing.

4. In' a therapeutic appliance a jacketed casing, inlet and outlet pathsfor distributing cooling fluid through the jacket of said casing, asource of ultra-violet light in said casing, an opening in said casing,an iris dia hragm across said opening, and a pipe to t 6 interior ofsaid casing.

5. A therapeutic apparatus including a holder member having an aperturefor ap- 5 plication to the part to be treated, a source of ultra-violetlight Within said holder and means for applying a gas under pressure tothe part to be treated at the area confined by said 0 ening, andadjustable means for vagying t e size of said opening. 10 igned atHoboken in the county of Hudson and State of New Jersey this 28th day ofNovember A.
